Description

[Detailed description of the invention] The present invention relates to a door roller for sashes without rails, and the engaging pieces are automatically engaged with the guide pieces provided on the lower frame of the sash when installing the shoji. This is a simplified version of .

The drawing shows an embodiment of the rail-less sash door roller according to the present invention, A is the door roller, and the main frame 1 of the door roller A is shown.
A gap 2 with an open bottom is formed in the gap 2, a wheel 3 is inserted into the gap 2, the wheel 3 is rotatably supported on the main frame 1 by a main shaft 4, and a notch 5 is formed on the other side of the main frame 1.
An engagement device 6 is provided in the notch 5, and the engagement device 6 has an intermediate portion of a lever 8 of a connecting member 7 rotatably pivoted to the main body frame 1 by a support shaft 9. 8 to one of the side pieces 11 and 12 of the engagement piece 10
One end of the support shaft 14, which is passed through the vertically elongated hole 13 provided in the main body frame 1 at a position corresponding to the extension line of the elongated hole 13 in the side pieces 11 and 12 of the engaging piece 10, is inserted into the main frame 1, and the other end is inserted into the main frame 1. The supporting shaft 14 has an end fixed to an assembly plate 15 attached to the main body frame 1, rotatably pivots the engagement piece 10 to the main body frame 1, and supports the engagement piece 10.
A coil spring 16 is wound around the coil spring 16, one end of the coil spring 16 is attached to the main frame 1, and the other end is attached to the engagement piece 10.
The tip 17' of the center piece 17 of the engaging piece 10 is engaged with the other side piece 12 of the sash lower frame 18.
The engaging piece 1 is disengaged from the guide piece 19 provided in the
0 is rotationally biased, a wheel 20 is rotatably attached to the other end of the lever 8, and the wheel 20 projects downward from the wheel 3.

Therefore, when the shoji is installed, the load of the shoji is applied to the rolling wheels 20, and therefore, the lever 8 of the connecting member 7 rotates about the support shaft 9, and one end of the lever 8 is passed through the vertically long hole 13. Therefore, as the one end descends, the engaging piece 10 rotates about the support shaft 14 against the coil spring 16, and the center tip 17' of the engaging piece 10 moves against the guide piece 19 of the sash lower frame 18. The coil spring 16 returns each member to its original position when the shoji is engaged to complete the erecting operation of the shoji, and when the shoji is released.

Incidentally, reference numeral 21 in the figure is an adjustment block through which the main frame 1 is vertically movably engaged with the mounting frame 22.
A vacant room 2 consisting of a mounting frame 22 and an assembly plate 15
A pair of connecting pins 24, 24 are attached to this adjustment block 21, and both ends of the connecting pin 24 are formed in the mounting frame 22 through horizontally long holes 25 provided in the main frame 1. A connecting pin 24 that engages with the oblique elongated hole 26 and runs along the elongated holes 25 and 26.
That is, the tip of the adjustment screw 27 for controlling the vertical movement of the main frame 1 is screwed into the adjustment block 21, the head 27' of the adjustment screw 27 is locked to the assembly plate 15, and the adjustment screw 27 The door roller A of the embodiment is constructed by fixing an exterior frame 29 provided with a window hole 28 for operation to the main frame 1 with screws 30.

In the figure, 31 shows the lower stile of the inner sash, 32 the lower stile of the outer shogi, and 33 a through hole for screwing.

Since the present invention has the above-mentioned configuration, the rolling wheels come into contact with the top surface of the sash bottom frame when the shoji is installed.
The other end of the lever relative to the wheel-side end presses the engagement piece against the coil spring, and the engagement piece rotates toward the sash lower frame and automatically engages the guide piece of the sash lower frame. can be engaged with. That is, the present invention is suitable for use as a door roller for a sash without rails because the engaging piece automatically engages with the guide piece when the shoji is installed.
